The HPV Serology Laboratory is leading a global partnership initiative aiming for standardization and harmonization of current serology assay platforms being used to assess immune responses to HPV vaccines. Serology standardization is particularly important given the increasing number of immunobridging trials relying on serology data for approval of new vaccine dosing schedules or vaccine formulations. The initiative was established in 2017 to enable comparisons of data between different vaccines and relevant studies as well as expedite the implementation of new vaccines and vaccine indications. The HPV Serology Laboratory has held or attended several meetings with partnering laboratories, including international meetings in 2017, 2018, and 2021.

The protective effect of naturally acquired humoral immunity against human papillomavirus (HPV) infection remains unclear. To investigate the role of infection-induced antibodies on HPV detection in heterosexual partners, we used data from 392 unvaccinated couples (females aged 18-25 years attended up to six visits over 2 years; males aged 17-37 years attended up to two visits 4 months apart) enrolled (2005-2011) in Montreal. Genital and blood samples were HPV DNA genotyped and tested for L1 antibody titers of 14 HPV genotypes.

Background: The humoral immune response against human papillomavirus (HPV) has been suggested as a source of biomarkers for the early detection of cervical cancer (CC). Therefore, we aimed to characterize the antibody response against HPV16 E5 in the natural history of cervical cancer and to determine its usefulness as a biomarker of HPV-associated cervical lesions.
Methods: This study was conducted at the Cuautla General Hospital, Morelos, Mexico, with women (18 to 64 years) who agreed to participate.

Introduction: Immunocompromised persons are at high risk of persistent Human Papilloma Virus (HPV) infection and associated diseases. Few studies evaluated HPV vaccines in immunocompromised persons. This study aimed to evaluate the quadrivalent HPV vaccine (4vHPV) immunogenicity and safety in solid organ transplant (SOT) recipients, in comparison to immunocompetent women (IC).
